datetick seems a good place to start. Otherwise you can see if the xtickformat function suits your need.

clc;clear; close all
startDate = datenum('01-01-2009');
endDate = datenum('12-31-2009');
xData = linspace(startDate,endDate,10);% changed to match size of data
plot(xData,rand(10));
%set(gca,'XTick',xData);  %maybe not necessary?
datetick('x','dd-mmm','keepticks');

MATLAB: Problem with xlim when having date

Hi Behzad,

xlim sets the absolute max and min of the graph that you're looking at. To set the interval for grid lines, use the xticks command.

For your needs, use this with the datetick command:

% Define specific five year spacing of ticks for the 27 years of interest
xtks = linspace(startdate_A,enddate_A,27);
plot(dt_A, DATA_A);
xticks(xtks); % Set ticks for axis
xlim([startdate_A,enddate_A]) % Set limits
datetick('x','yyyy','keepticks');
grid on
